first embodiment
[0032]FIG. 2 is a block diagram showing the configuration of a recorder / reproducer equivalent to the invention and FIG. 3 explains data processing in this embodiment. The recorder / reproducer in this embodiment is substantially composed of a parabolic antenna 2, a digital satellite broadcasting receiving board 6, a bus arbiter 7, CPU 8, a system memory 9, a storage device 10, graphics 11, a frame buffer 12, a sound processor 13 and an internal bus 14 as shown in FIG. 2. Further, the digital satellite broadcasting receiving board 6 is composed of a tuner unit 15, a descrambling unit 16 and a PID filter 17.
[0033]The digital satellite broadcasting receiving board 6 is mounted inside the personal computer 3, is controlled by CPU 8 via the internal bus 14, processes a radio wave from the satellite received via the parabolic antenna 2 and outputs a picture signal and an aural signal.
[0034]In the digital satellite broadcasting receiving board 6, the tuner unit 15 demodulates a radio wave re...
second embodiment
[0057]FIG. 4 is an explanatory drawing for explaining data processing in a recorder / reproducer equivalent to the invention.
[0058]The whole configuration of the recorder / reproducer equivalent to this embodiment is different from that in the first embodiment only in that a system memory 9A is provided in place of the system memory 9 shown in FIG. 2 in the first embodiment.
[0059]Referring to FIG. 4, the features of a program stored in the system memory 9A in this embodiment will be described below. The configuration and feature of a parabolic antenna 2, a digital satellite broadcasting receiving board 6 and a storage device 10 respectively shown in FIG. 4 are similar to those in the embodiment shown in FIG. 2.
[0060]A program for realizing a recording / reproducing feature in the system memory 9A is composed of a program information management division 24, a recording / reproducing management division 25A, a data control division 26 and an MPEG2 decoder 27. Of these, the features of the pro...
